No, not really. There was no alternative to a mobile phone back then. The alternative now is a charged battery or an external battery pack.
I see where you are going with this.
But there were alternatives to cell phones back then. There were car phones (my stepfather had a dial one in 1983. Not touch tone, but it looked like a standard phone that was bolted in the car that made calls while he was driving. It was probably the precursor to today's "no phones while driving" laws)
The other alternatives were phone booths and the home phone.
Anyway, the alternatives you mention are good, even better than this technology, so you are probably right. New technology has to be better than the current technology. Then, the builders can command a premium price. Otherwise, it's a flop.
